I've been part of jawug (http://www.jawug.za.net) for quite a while now. Basically its a community wireless network based on 802.11 standards.
After jawug, there was another community formed wug (http://www.wug.za.net) whose aim was to provide a common place for all wugs (wireless user groups) from around South Africa (and even Namibia) to communicate and coordinate.
If you are interested in joining a wireless community network, visit the two sites and read about it. Its really great, because essentially you have a big LAN and people have resources available on the network. The guys run email servers, web servers, ftp servers. Things like an asterisk server for SIP phone calls between the nodes and irc servers. Bittorrent trackers. The possibilities are really endless! Not to mention the game servers (counter strike, warcraft3 - and any game you want to play!) and of course all the series and movies you want to download! soo, anyways, its a great bunch of people who have a great bunch of movies :)
I used to run a 3 way node about a year ago. I was a master and Ivan, dorris and Silver were connecting to me. Recently, there has been a HS (High Site) put up at Grand Central and I am pretty sure I will be able to see it. It runs on 5.8ghz range.
I got my 5.8 equipment (hot routerboard 333) and a 27dbi grid. Although I cant see Grand Central. There may actually be a problem with the sector / radio at Grand Central and we will be checking that hopefully this weekend.
The bottom line is, once i'm connected to the Grand Central HS (its about a 12km link). I will be in the jawug backbone, as Grand Central connects to Kempton Park with the HS on the Trust Bank building.
I also have a 2.4 patch which i will let people connect to me if they are in the lonehill, sunninghill, paulshof area. Basically anyone that can see me can connect and join the Jawug backbone.
So thats my news. I'll let you know when we fix Grand Central and hopefully i see it!
